861: (311/365) Tessellated Star Box

I saw a photo sequence of a tessellation that was fashioned into a box and knew I had to try it:

Well, I say tessellation, but really this is just one molecule, but it is none the less beautiful. Continue reading

851: (301/365) Vale Vicky

People process loss in different ways. 10 years ago a friend lost her fight with cancer and I am still saddened by the loss of such a bright and affirming soul:

While I could not bring myself to attend a memorial mass, none the less I still feel the loss. I chose to find solace in the many wonderful memories of a friend and confidante. Continue reading

791: (241/365) Flower Tessellation

Browsing a MiniNeo eZine that I follow, I noticed a rather interesting looking hexagonal flower and thought it worth a try:

You triangle grid a hexagon into 16ths, then put a hex twist in the middle, then add the swing-back on petals and tidy up the tessellation to make a swirl. Continue reading

787: (237/365) Daffy Down Dilly

Today (August 25) is Daffodil Day, daffodils being the icon associated with cancer awareness and fundraising for an eventual cure. You can get involved, donate or buy badges and sponsored bunches of flowers to show your support:

This seems to be a traditional model (sorry, I have yet to identify the designer) but is related to folds I have been exploring for a week or so based on non-squares. Continue reading

786: (236/365) Beth Johnson’s Hex Owl

I cannot believe I have not tried this before:

A lovely hexagonal tessellation in one corner of a hexagon becomes the fluffy tummy, collapsing the body makes for lovely eyes and a pair of crenellated wings. Continue reading

662: (112/365) Spiral Corrugation

Origami seems to be the new Materials Engineering black, being considered a contemporary alternative approach to fabrication and structure:

I was reading an article on deploying large solar arrays in space. This problem is not unique – everything taken into space must be small at launch so it can fit in a rocket. Continue reading

Folding Algorithms – Sato Rose

Much of Origami is algorithmic (algorithm = procedural solution to a problem). A rabbit ear is an algorithm, one knows how to fold it on a corner – double rabbit ear is the same solution, folded two simultaneously. Petal fold is also a standard maneuver which got me thinking of the Sato Rose algorithm.

I like this algorithm particularly because of the free-form nature of much of the folding, and the way it seems to “fit” a pentagon. I decided to use the same folding algorithm but try it with other regular polygons – I tried triangle(3), square(4), pentagon(5), hexagon(6), heptagon(7), octagon(8), nonagon(9) but gave up on the decagon(10).

The algorithm involves “nearly” bisecting each vertex to form an echo shape at the centre of the sheet – you then halve that internal echo to create a slightly offset echo and use that as the basis of a “kawasaki twist” Continue reading

238: Daffodil Day

In Australia, August 26 this year is nominated as “Daffodil Day”:

We celebrate the lives of those brave people who have fought cancer in all it’s forms – to do so we use a flower, the fragile symbol of hope and beauty:

I made a white one, then folded 4 in colour and scattered then strategically around my school. I remembered, if few others did initially. I do this in memory of some dear friends that lost the fight and suffer no more.

A complex and time-consuming fold,  the flower head is dense and made, unusually from a hexagon cut from an A3 sheet, it collapses down to a life-size bloom via some interesting sinking, swivels and squash folds. An interesting (and cathartic) fold designed by Paul Jackson, taken from a book loaned to me by Amanda (thanks @ackygirl)

I hope you remembered Daffodil Day, or at the very least people you know who have been touched by Cancer.

95: Star Puff tesselations

I am fairly new to box pleating and tessellated patterns but this one caught my eye and I had to try it:

Oddly, it works on 120 degree angles, so a hexagon is perfect as a starter. I would like to say it was all neat and went to plan, but the individual “triangle twists” are not as even as I would like (I put that down to having no idea what I was doing initially) – certainly they got better the more of them I completed:

I get the impression that the smaller the pleats, the more of the units fit, but the more complex the interaction between them so you get folded into fiddly corners. I quite like the triangle twist method, some pleasing shapes emerge from it.

You should give this a try – do not be frightened by the link, the instructor speaks English amidst the sea of German: star puff
